If you run Netbeans 6.1 on Opensuse 11, you will get the IDE is blank. This happen because you are using compiz desktop effect. You must disable this feature via 'Simple CompizConfig Setting Manager'. To do this you go to 'Control Center' under 'Look and Feel' click 'Simple CompizConfig Setting Manager' and uncheck 'Enable desktop effects'. Now you Netbeans will display IDE correctly.
